RLL Select-Fire kit with 9mm host

[beltfed]

I don’t understand, or I can’t picture what could be happening. I could give you a measurement off my disconnector to get the correct depth of cut. I would still suggest if you have not tried this is to check the travel and contact on the disconnector. With the upper lifted up so you can look down into the lower push the link all the way back until it can’t move any more it should not have made contact with the left side semi disconnector.

Question with gun “ unloaded” in the semi position and hammer cocked pull trigger hammer drops hold trigger back pull bolt back to reset hammer and let bolt slam closed did trigger drop ?

The problem I have with this is that you’re saying the carrier is hitting the link so hard that it is somehow tripping the semi disconnector

I sorry if this is stuff you have already tried but I’m just trying to help.
